It would be GREAT to get announcments and working departure boards! I know departure boards could be kinda hard to create, but these are the detail that really create an immersive experience with the game. On-board train announcements ( next station, the station we are currently at, train being late ) would help with creating an immersive experience, too! I don't know much about creating games, but it sounds much easier to do, than departure boards. You would only need someone to record these, or even use an Ivona text reader.
